first off please reconsider teh whole NE thing because everyone and their mother has a NE rogue.
If you want to use other weapons instead of daggers, i would go human for the mastery that they start off with. If you are going for an engineer rogue (best proffession for rogue imo) then go gnome.
I personally have a human rogue with a dagger in the main hand and a sword in the other. reason i dont go for mace is because the attack speed with swords are faster.
If i had a troll, i would have gone dual mace and abuse slice and dice + berzerker rage. now THAT is abusive.
